Tuam Tshoj Boron Nitride Ceramics
Boron nitride ceramic yog ib yam khoom ua los ntawm cov khoom zoo boron nitride ua raw khoom. Nws txais cov yam ntxwv ntawm cov khoom siv tshwj xeeb no, qhia qhov zoo ntawm qhov kub thiab txias, tsis muaj kev sib txuas, corrosion kuj, kub dissipation thiab thermal conductivity. Txij li nws muaj ntau yam zoo, kev siv boron nitride ceramics kuj muaj ntau qhov xwm txheej.
Boron nitride ceramics tuaj yeem siv los ua cov cuab yeej siv ceev ceev thiab laum cov khoom siv rau kev tshawb nrhiav geological thiab roj drilling, vim tias boron nitride ceramics tsis ntub dej nrog txhuas thiab muab kev tiv thaiv zoo rau cov khoom siv hauv kev sib cuag nrog molten aluminium, magnesium, zinc. alloys thiab lawv melting slags.
Tsis tas li ntawd, cov duab ntawm boron nitride ceramics tuaj yeem sib txawv, yog li nws tuaj yeem ua rau kub kub, kub siab, rwb thaiv tsev, cua sov dissipation qhov chaw; Los yog ntim cov ntaub ntawv los tiv thaiv cov hluav taws xob neutron; Thiab tshwj xeeb electrolysis thiab cov ntaub ntawv tiv thaiv uas tuaj yeem siv rau qhov kub thiab txias.
Nws tau hais ntxiv tias cov ntaub ntawv kub kub insulating yuav tsum ua kom tau raws li qhov yuav tsum tau ua ntawm qhov siab melting point, tsim nyog lub cev muaj zog tiv thaiv thiab tshuaj lom neeg sib raug zoo ntawm qhov kub thiab txias. Boron nitride ceramics haum rau daim nqi, muaj ob qho tib si lub siab melting point thiab txiav txim siab resistivity ntawm qhov kub thiab txias. Tshwj xeeb tshaj yog cov hexagonal daim ntawv qauv ntawm boron nitride ceramics muaj qhov zoo ntawm kev sib txhuam coefficient ntawm qhov kub thiab txias, thermal expansion coefficient zoo ib yam li tungsten, kub xovxwm thaiv yuav tig, yog li nws yuav dhau los ua ib qho zoo tagnrho kub insulating khoom.
